Friday 17 November, 2017 Update: Argentine Submarine Missing


The fate of the Argentinian submarine ARA San Juan remains unknown this evening. The diesel sub has been missing for two days. The last communication between San Juan and higher headquarters was on Wednesday. She was in the area of San Jorge bay at the time. Although an Argentinian Navy spokesman told local television that the sub cannot be considered lost yet, the search was formally classified as a search and rescue operation earlier tonight. A NASA P-3C Orion that was in Argentina for an unrelated exercise was offered by the US to assist in the search. Buenos Aries accepted the offer and the Orion is actively taking part in the operation. Brazil, Uruguay, Chile, Peru, Britain and South Africa have also formally offered assistance. A Chilean patrol aircraft is on its way to join the search at the moment. It is unclear whether or not Argentina has accepted any other offers of assistance.

The search efforts are being hampered by high winds and rough seas in the area. Time is critical in an active search and rescue operation involving a sub potentially in danger. The longer the search drags out, the more likely it becomes that San Juan has suffered a catastrophic malfunction, or other type of emergency.

San Juan is a diesel-electric submarine built by Thyssen Nordseewerke in Germany. She was commissioned in 1985 and served without major issue. Her mid-life upgrade took place between 2008 and 2013. Since then San Juan has taken part in routine operations and exercises in the waters around Argentina. She has a compliment of 37 but was carrying a slightly larger crew of 44 during this cruise.
